Prepared myself for the experience by eating some hash beforehand, was nicely & profoundly monged by the time I turned up at the place.

Got undressed, climbed in, my stoned mind was racing in a million different directions and it took me a long, long time to get used to the strangeness of the tank and calm down.

Just as I was starting to really get into it, the most hideous music imagineable started playing, like the worst kind of cheesy New Age dolphin whalesong bullshit that you hear in shops that sell scented candles.

I spent the rest of the time hating the music and feeling totally pissed off, couldn't wait to get out of the tank.

I asked the woman wtf afterwards, and she said the tanks can sometimes freak people out, and they always play music at the 30 minute point of a 1-hour session. If you don't want them to, you have to ask them beforehand. She then directed my attention to a large sign above the counter spelling all this out, which I hadn't noticed.
